The transverse mass distributions are rapidity independent within |y|<0.5, consistent with a boost-invariant system in this rapidity interval. Spectral shapes and relative particle yields are similar in pp and peripheral Au+Au collisions and change smoothly to central Au+Au collisions. No centrality dependence was observed in the kaon and antiproton production rates relative to the pion production rate from medium-central to central collisions. Chemical and kinetic equilibrium model fits to our data reveal strong radial flow and relatively long duration from chemical to kinetic freeze-out in central Au+Au collisions. The chemical freeze-out temperature appears to be independent of initial conditions at RHIC energies.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.100591.v1/t1","@type":"Dataset","description":"invariant yield as function of transverse mass for $\\pi^{\\pm},K^{\\pm}$ and inclusive $p$ and $\\bar{p}$ at mid-rapidity ($|y|<0.1$) for pp (bottom)...","name":"Figure 1-1"},{"@id":"https://doi.org/10.17182/hepdata.100591.v1/t2","@type":"Dataset","description":"invariant yield as function of transverse mass for $\\pi^{\\pm},K^{\\pm}$ and inclusive $p$ and $\\bar{p}$ at mid-rapidity ($|y|<0.1$) for pp (bottom)...","name":"Figure 1-2"},{"@id":"https://doi.org/10.17182/hepdata.100591.v1/t3","@type":"Dataset","description":"invariant yield as function of transverse mass for $\\pi^{\\pm},K^{\\pm}$ and inclusive $p$ and $\\bar{p}$ at mid-rapidity ($|y|<0.1$) for pp (bottom)...","name":"Figure 1-3"},{"@id":"https://doi.org/10.17182/hepdata.100591.v1/t4","@type":"Dataset","description":"Rapidity distributions of the fiducial yields and integrated $$ for the $0-5\\%$ and $70-80\\%$ Au+Au collisions.
